Download As A PDF

The UK formally departed the European Union at midnight CET on 31st December 2020.

The European Union Trade and Cooperation Agreement was finalised on 24 December 2020, setting out the future relationship.

Agreements reached between the United Kingdom of Great Britain and Northern Ireland and the European Union - GOV.UK (

European Chemical Regulation was retained in GB Law at the time of departure, which is reflected in GB legislation:

This new GB legislation retains the fundamentals set out by the EU on REACH, Biocides, etc., but divergence could follow with future revisions. For example, differences in those substances considered as Candidate List substances of Very High Concern for authorisation of use.

CHCS expect more information and guidance to become available in the coming weeks to explain the outcome of the future relationship between the Member States of the European Union and the United Kingdom on chemical regulation.

In the meantime, we are pulling together information and providing links to information sources within this Brexit section of the website.

The information covering GB REACH is more developed, as information and guidance on this aspect of GB regulation post Brexit was made available earlier by the UK government.
